Re: Convert M4B to a playable format?

M4B is a great format for keeping bookmarks of audiobooks, the only problem is that some players or devices don't support it so well. So you can convert to a playable format, I will recommend you to try to convert M4B to MP3 or AAC. If you are interested, you can take a look at the tutorial. As a music lover, I have tried multiple ways to convert my music and audiobooks, this turns out to be a best way for me.
